This shot is trying to portray hysteria. A small corner is shown to indicate that the setting is small and cramped which might have been one reason why this person is going mad. The body language is very messy which connotes what is going on inside this individuals head(messy,mixed thoughts allowing her to be all over the place). Her hands are on her head to convey the madness along with the angry facial expression that shows she is experiencing pain and as there is no one else seen in the shot; this also suggest that she is lonely and depression could have led to this. This shot is a medium shot which captures the main aspects (body language/facial expression) to show hysteria. As she is sitting on the floor, this makes her seem vulnerable and weak because it seems as though she can't control herself and just huddles up by herself for protection.
